Topical fluoride applications in the form of varnishes and gel may lead to deposition of fluoride on enamel.<\/jats:p><jats:p>Purpose: This in vitro study aimed to evaluate the effect of two fluoride varnishes and one fluoride gel on the dissolution of bovine enamel by acids.<\/jats:p><jats:p>Methods: Enamel samples (72) were divided (<jats:italic>n<\/jats:italic> = 8): artificial saliva (control\u2010G1), Pepsi Twist\u00ae (G2), orange juice (G3), Duraphat\u00ae + Pepsi Twist\u00ae (G4), Duraphat\u00ae + orange juice (G5), Duofluorid\u00ae + Pepsi Twist\u00ae (G6), Duofluorid\u00ae + orange juice (G7), fluoride gel + Pepsi Twist\u00ae (G8), and fluoride gel + orange juice (G9). Fluoride gel was applied for 4 min and the varnishes were applied and removed after 6 h. The samples were submitted to six cycles (demineralization: Pepsi Twist\u00ae or orange juice, 10 min; remineralization: saliva, 1 h). Samples were analyzed by energy\u2010dispersive X\u2010ray fluorescence (144 line\u2010scanning).<\/jats:p><jats:p>Results: The amount of Ca and P decreased significantly in the samples of G2 and G3, and the Ca\/P ratio decreased in G3. Mineral gain (Ca) was greater in G9 samples than in G4 &gt; G3 &gt; G5 &gt; G1, and (P) greater in G7 samples than in G9 &gt; G4\u20106 &gt; G2\u20103.<\/jats:p><jats:p>Conclusions: The protective effect of Duofluorid\u00ae was significantly lower than fluoride gel against orange juice. The fluoride varnishes can interfere positively with the dissolution of dental enamel in the presence of acidic beverages. Fluoride gel showed the best protection level to extrinsic erosion with low costs. Microsc. Res.
